SWEEP.

Application filed August 25, 1924. Serial No. 734,108.

To all whom it may concern. V Be it known that I, JOHN G. SWEIGARD, a citizen of the United States, residing at lVinside, in the county of Wayne and State of Nebraska, have invented new and useful Improvements'in Sweeps, of which the following is a specification.

My present invention has reference to a sweep for harrows, and my object is to produce a sweep comprising a main section and auxiliary sections which are hingedly secured to and designed to be arranged coextensively with the main section, whereby a comparatively long sweep will be pro duced, and also whereby the auxiliary sections may be folded over the mainvsection when the sweep is passed through gateways, over bridges or other restrictedareas.

The invention further consists in the construction, combination and operative association of parts such as is set forth in the fol lowing description, shown by thedrawings and set forth in detail in the appended claim.

In the drawings Figure 1 is a top planview of the improvement.

Figure 2 1s a rear edge-view thereof, the,

dotted lines showing one of the auxiliary sect-ions about to be swung over the main section of the sweep.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

The main section of the sweep is indicated by the numeral 1, and the end auxiliary sections by the numeral 2 respectively. The end or auxiliary sections 2 are hingedly con: nected to the top and at the ends of the main section 1, as indicated by the numeral 3. By such arrangement it will be noted that the auxiliary sections 2 may be swung over the main section 1 when the length of the sweep is to be decreased, and that when the said auxiliary sections are swung outwardly, on the main section 1, the length of the sweep is materially increased.

Secured on the outer face and at the ends of the main section 1 there are hollow metal members 4, each of which projects a suitable distance beyond the end of the said section 1. The members 4 serve as abutment elements for the auxiliary or end sweep sections 2 when the latter are arranged co-extensi'vely with the section 1.

All of the sections have on their inner edges or faces hooks 5 to be engaged by the harrows.

Arranged over the metal abutment blocks 4 and over each of the end sections 2 there is a yoke. The yoke preferably comprises upper and lower bars 6 respectively con nected together at their ends by bolts 7 and 8. The bolts 7 are designed for contacting engagement with the outer faces of the abutment blocks 4. Between the arms 6 of each of the yokes there is arranged what I will term a saddle member 9, and each of the saddle members has its outer face bifurcated. Pivotally secured inthe bifurcated rear por tion of each of the saddle members 9 there is a lever 10. The lever has an offset head 11 in the nature of a cam element which is designed to be brought into contacting engagement with the bolt 8 of the respective yokes when the levers are in looking position as illustrated in the figures of the drawings. Each of the levers is designed, when in such position to contact with the lug 12 on the inner edge or face of the auxiliary or end sweep sections 2. By reference to Figure lof the drawings, it will 'be noted that the pivotal connection of the levers 10 with the yokes 9 is disposed outwardly with respect to the contacting engagement with the cam heads 11 of the said levers with the bolts 8 of the yokes so that liability of accidental operation of the levers will be thus overcome.

From the foregoing description when taken in connection with the drawings it will be noted that the sections 2 are effectively locked on the section 1 when the sweep is in extended position. It will be apparent that by swinging the levers 10 tobring the cam heads thereof out of engagement with the bolts or ends 8 of the yokes, the yokes may be readily brought out of engagement with the metal blocks 4 which permits the ends 2 being swung over the main section 1, so that the sweep may pass along roads between fences, through gateways, over bridges and over other restricted trafiic sur faces.

Having described the invention, I claim A sweep for harrows comprising a main section, auxiliary sections hingedly secured to the upper face at the ends of the main section, hollow metal blocks on the outer face of the main section projecting beyond the ends thereof and against which the auxiliary sections contact when arranged coextensive with the main section, yokes straddling the blocks and the auxiliary sections, a saddle in each of the yokes contacting with the auxiliary sections, cam levers pivotally secured to the saddles engageable with one end of each of the yokes, and stop blocks on the auxiliary sections for limiting the swinging of the cam levers in yoke en 10 gaging position.

In testimony WhereofI aliix my signature.

JOHN G. SVVEIGARD.
